Ryan R. Martin I am a professor at Iowa State University and currently a Scott Hanna Professor. I am Editor-in-Chief of the journal Order, published by Springer. My research is partially supported by a grant from the Simons Foundation (#709641, 2020-2025). My fields of interest are extremal poset theory, graph theory and extremal and probabilistic combinatorics.
The discrete mathematics research cluster is partially supported by Research Training Grant (RTG) #1839918 from the National Science Foundation (NSF). My research is partially supported by a grant from the Simons Foundation (#709641, 2020-2025) I received an award from the Distinguished Guest Fellowship Programme in Hungary by the Hungarian Academy of Sciences (MTA) and was based at the Alfréd Rényi Institute of Mathematics in Budapest from July 2023 through January 2024. I was a visitor of Maria Axenovich at the Karlsruhe Institute of Technology, Germany via the German Academic Exchange Service (DAAD) in 2020. I was a Fulbright US Scholar as part of the Budapest Semesters in Mathematics program at the Alfred Rényi Institute of Mathematics in 2019.
